Flat sheet membrane
High permeability membranes using a hydrophilic material
Made of PES (Polyethersulfone), a hydrophilic polymer material, Neofil flat membranes provide more excellent fouling resistance and water permeability in environments treated with high concentration activated sludge such as sewageㆍwastewater treatment processes, unlike hydrophobic polymer materials (PTFE, PP, etc.).
Due to excellent water-friendly properties, excellent selective permeability in high-concentration sludge environments
Excellent fouling resistance in high concentration environment due to low adsorption of organic matter such as protein and microorganism
Unlike hydrophobic polymer materials, pretreatment such as hydrophilization is not required, making product handling easy.
Pure Permeability
| Category | Contact angle | Pure permeability |
| Hydrophilic membrane | 58.3° | 4,375LMH |
| Hydrophobic membrane (PP) | 64.9° | 3,844LMH |
Excellent adhesion between flat sheet membrane and panel
Made with a thermal bonded facility specialized for membrane sheets and ABS panels, the flat membrane module is a product that can be used even in harsh conditions by securing excellent durability and excellent adhesion.
